And, behold, two blind men sitting by the way side, when they heard that Jesus passed by, cried out, saying, Have mercy on us, O Lord, thou Son of David. Two blind men - Mark 10:46, and Luke 18:35, mention only one blind man, Bartimeus. Probably he was mentioned by the other evangelists, as being a person well known before and after his cure. Blindness of heart is a disorder of which, men seldom complain, or from which they desire to be delivered; and it is one property of this blindness, to keep the person from perceiving it, and to persuade him that his sight is good.
Sitting by the way side - In the likeliest place to receive alms, because of the multitudes going and coming between Jerusalem and Jericho.
Cried out - In the midst of judgments God remembers mercy. Though God had deprived them, for wise reasons, of their eyes, he left them the use of their speech. It is never so ill with us, but it might be much worse: let us, therefore, be submissive and thankful.
Have mercy on us - Hearing that Jesus passed by, and not knowing whether they should ever again have so good an opportunity of addressing him, they are determined to call, and call earnestly. They ask for mercy, conscious that they deserve nothing, and they ask with faith - Son of David, acknowledging him as the promised Messiah.
